Description: AJMP unconditionally jumps to the indicated code address. The
new value for the Program Counter is calculated by replacing the
least-significant-byte of the Program Counter with the second byte of the
AJMP instruction, and replacing bits 0-2 of the most-significant-byte of the
Program Counter with 3 bits that indicate the page of the byte following the AJMP instruction.
Bits 3-7 of the most-significant-byte of the Program Counter remain unchaged.

Since only 11 bits of the Program Counter are affected by AJMP, jumps may only be
made to code located within the same 2k block as the first byte that follows AJMP.
